Basic Power Supply Module (incl box)
 
Batteries soon become an expensive way to power your electronic kits and electronic games. This is a basic power supply in a box using two 7805 regulators. Input up to 20V AC from a transformer or power pack. Two regulated outputs are available - one fixed at 5V, the other variable. Good introduction to three terminal regulators.(CPS4)

Bidirectional DC Motor Speed Controller
 
This kit allows controlling the speed of a DC motor in both the forward and reverse direction. The range of control is from fully OFF to fully ON in both directions. Normally, switches are used to change the direction of rotation of a DC motor. Change the polarity of the applied voltage and the motor spins the other way! However this has the disadvantage that a DPDT switch has to be added to change the polarity of the applied voltage. Now you have two things to control the motor – a direction switch as well as the speed control. Also, it is not a good idea to suddenly reverse the voltage on a DC motor while it is spinning. It can cause a current surge that can burn out the speed controller. Not to mention any mechanical stress it can cause as well. PCB size: 93mm x 42mm (3.625 x 1.625 inch) (CPS166)

TDA2002 / TDA2003 Amplifier Module kit
 
A proven & popular power amplifier building block for use in any audio project. Power output is dependent on the supply voltage and load resistance. Over 10W is typical for a 16V supply into a 2 ohm speaker. A 12V supply into a 4 ohm speaker will deliver around 4W. Small heatsink provided. In late 2000 the LM383 was discontinued but the TDA2002 is a direct replacement for the LM383. (CPS47)

USB EXPERIMENT INTERFACE BOARD
 
The K8055 interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (98SE, 2000, Me, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. (K8055)
